DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3 of the drawings, an epilation apparatusaccording to a preferred embodiment of the present invention isillustrated, wherein the epilation apparatus is arranged for holding athread 10 in position to complete the threading operation. The epilationapparatus comprises a body 20 and a thread operating device 30.

The body 20 comprises a housing 21 defining a front side 211, and twospaced apart holding arms 22 frontwardly extended from the front side211 of the housing 21. The housing 21 has a receiving cavity therein toreceive the thread operating device 30. In particular, the two holdingarms 22 are integrally extended from the housing 21 to define two freeends of the holding arms 22. Accordingly, the two holding arms 22 areimmovable with respect to the housing 21 that a distance between thefree ends of the holding arms 22 are fixed.

The thread operating device 30 comprises a powering unit 31 supportedwithin the housing 21 of the body 20 and a rotatable arm 32 extendedfrom the body 20 between the holding arms 22. In particular, therotatable arm 32 is extended from the front side 211 of the housing 21at a position between the holding arms 22.

As shown in FIGS. 1 to 3, the thread 10, such as a cotton thread, isheld by the epilation apparatus by a three-point support. Two free endsof the thread 10 are detachably coupled at the free ends of the holdingarms 22 respectively. A mid-portion of the thread 10 is detachablycoupled at the free end of the rotatable arm 32. In other words, thethread 10 is held in a V-shaped configuration. When the rotatable arm 32is driven to reciprocatingly rotate by the powering unit 31, themid-portion of the thread 10 is twisted to simulate a threading motion.Therefore, by placing the thread 10 on the skin of the user, thethreading motion of the thread 10 will trap hairs in the twisted thread10 and will pull the hairs out.

It is worth mentioning that the two holding arms 22 are immovable suchthat only the mid-portion of the thread 10 is twisted by the rotatablearm 32 so as to provide a stable threading operation. In addition, thetwisting motion of the thread 10 will minimize the tension of the thread10 to prevent the thread 10 from being broken.

As shown in FIGS. 1 and 4, the body 20 further comprises a through slot23 provided at the front side 211 of the housing 21 at a positionbetween the holding arms 21, wherein the through slot 23 is arranged tocommunicate with the receiving cavity of the housing 21. In particular,the rotatable arm 32 is aligned with the through slot 23 such that themid-portion of the thread 10 can couple at the free end of the rotatablearm 23 through the through slot 23. The rotatable arm 32 is also adaptedto be pulled out of the front side 211 of the body 20 through thethrough slot 23 thereof when the thread is twisted.

The front side 211 of the housing 21 is configured as a concave surface,wherein the through slot 23 is formed at a vertex of the concave frontside 211 of the housing 21, so as to maximize the distance between thefree end of the rotatable arm 32 and the free end of each of the holdingarms 22. In other words, the length of the thread 10 will be prolongedto enhance the threading operation.

As shown in FIGS. 2, 3 and 5, the powering unit 31 comprises a powersource 311 and a motorized unit 312 operatively linked to the powersource 311 for generating a reciprocatingly rotational power to therotatable arm 32.

The power source 311, which is supported within the housing 21,comprises a rechargeable battery and a charging outlet provided at arear side of the housing 21. It should be appreciated that the powersource 311 can be embodied as a battery compartment for receiving abattery thereat to operatively link to the motorized unit 312, whereinthe battery can be a disposable battery or a rechargeable battery.

The motorized unit 312 comprises an electric motor supported within thehousing 21 and an output shaft extended from the electric motor forgenerating a reciprocatingly rotational power. Accordingly, thereciprocatingly rotational power is transmitted to the rotatable arm 32in order to drive the rotatable arm 32 to rotate.

The powering unit 31 further comprises an operation switch 313 providedat the top side of the housing 21 and a circuit board 314 supportedwithin the housing 21, wherein the operation switch 313 is arranged toactivate the motorized unit 312 through the circuit board 314 in orderto drive the rotatable arm 32 to rotate. In particular, when adepression force is applied to the operation switch 313, the motorizedunit 312 will be activated. When the depression force is then applied tothe operation switch 313, the motorized unit 312 will be deactivated.

As shown in FIGS. 2 and 3, the rotatable arm 32 comprises a resilientarm 321 extended at the first side 211 of the body 20 for coupling withthe mid-portion of the thread 10, wherein the resilient arm 321 isarranged for applying a resilient force to the thread 10 toself-adjusting a tension of the thread 10 when the thread 10 is drivento twist. According to the preferred embodiment, the resilient arm 321is a compression spring having a front end as the free end of therotatable arm 32 to couple with the mid-portion of the thread 10.

Accordingly, when the mid-portion of the thread 10 is twisted, thethread 10 will be pulled against the free ends thereof. When asubstantial pulling force is applied to create large enough tension ofthe thread 10, the thread 10 will be broken. Therefore, the resilientarm 321 will form a buffering element to reduce the tension and tominimize the sudden pulling force at the thread 10.

In order to allow the mid-portion of the thread 10 being easily coupledat the free end of the rotatable arm 32, the body 20 further comprises athread coupling unit 24 for coupling the thread 10 with the rotatablearm 32. The thread coupling unit 24 comprises a folding tab 241, atubular arm sleeve 242, and an end blocker 243.

The folding tab 241 is foldably coupled at the housing 21 at the upperside thereof to communicate with the through slot 23, wherein thefolding tab 241 has an pusher arm 244 extended downwardly to the throughslot 23. Preferably, the folding tab 241 is pivotally coupled with thehousing 21, wherein the pusher arm 244 has a U-shaped configuration.When the folding tab 241 is pivotally and upwardly folded, the pusherarm 244 is driven to move frontwardly.

The arm sleeve 242 has a cavity to slidably and coaxially receive therotatable arm 32 therein , wherein the arm sleeve 242 has an operationslot 245 indently formed at the outer circumferential side of the armsleeve 242. The pusher arm 244 is engaged with the operation slot 245 tocouple the arm sleeve 242 with the folding tab 241. The arm sleeve 242is slidably supported in the housing 21 to encircle around the rotatablearm 32.

The end blocker 243 is coupled at the free end of the rotatable arm 32and is blocked by the front end of the arm sleeve 242 to retain the freeend of the rotatable arm 32 out of the cavity of the arm sleeve 242. Inother words, the size of the end blocker 243 is larger than the diameterof the arm sleeve 242 to prevent the end blocker 243 being slid into thearm sleeve 242. At the normal position, the end blocker 243 is held atthe front end of the arm sleeve 242 such that the free end of therotatable arm 32 is retained in front of the arm sleeve 242.

When the folding tab 241 is folded upwardly, the arm sleeve 242 ispushed frontwardly via the pusher arm 244 so as to push the end blocker243 frontwardly to expose the free end of the rotatable arm 32 out ofthe through slot 23. Therefore, the user is able to easily access therotatable arm 32 to couple the mid-portion of the thread 10 thereat.When the folding tab 241 is downwardly folded flat to align with theupper side of the housing 21, the arm sleeve 242 is moved rearwardly.Therefore, the end blocker 242 is move rearwardly to move the free endof the rotatable arm 32 back into the through slot 23. In other words,the free end of the rotatable arm 32 is hidden within the housing 21.

It is worth mentioning that when the resilient arm 321 is stretched toprolong the length thereof by the resilient force in response to thetension of the thread 10, the end blocker 243 is also pulled out of thethrough slot 23. However, the arm sleeve 242 is remained at its normalposition without being pushed frontwardly.

FIGS. 6A and 6B illustrate an alternative mode of the thread couplingunit 24A for coupling the thread 10 with the rotatable arm 32, whereinthe thread coupling unit 24A comprises an elongated operation slot 241Aand an operation tab 242A.

The operation slot 241 A is formed at the bottom side of the housing 21and is aligned with the through slot 23 thereat. In particular, theoperation slot 241A is a through slot to communicate the interior of thehousing 21.

The operation tab 242A which is coupled with the rotatable arm 32 and isslidably engaged with the operation slot 241A. In particular, theoperation tab 242A has an inner portion coupled with the rotatable arm32 and an outer portion slidably engaged with the operation slot 241A.In other words, when the outer portion of the operation tab 242A is slidalong the operation slot 241A, the rotatable arm 32 is driven to slidecorrespondingly.

As shown in FIG. 6A, the free end of the rotatable arm 32 is hiddenwithin the housing 21. When the outer portion of the operation tab 242Ais slid frontwardly along the operation slot 241A, the rotatable arm 32is driven to slide frontwardly until the free end of the rotatable arm32 exposes out of the through slot 23 as shown in FIG. 6B. Therefore,the user is able to easily access the rotatable arm 32 to couple themid-portion of the thread 10 thereat. When the outer portion of theoperation tab 242A is slid rearwardly along the operation slot 241A, therotatable arm 32 is driven to slide rearwardly such that the free end ofthe rotatable arm 32 is moved back into the through slot 23 as shown inFIG. 6A.

As shown in FIGS. 2 and 3, the rotatable arm 32 further comprises adriving arm 322 rearwardly extended from the resilient arm 321 tooperatively couple with the motorized unit 312 of the powering unit 31.In particular, the driving arm 322 is coupled to the resilient arm 321end-to-end. Accordingly, in order to operatively couple the rotatablearm 32 with the motorized unit 312 of the powering unit 31, a drive gearunit 323 is provided to operatively link the driving arm 322 with theoutput shaft of the motorized unit 312 as shown in FIGS. 3 and 5.Therefore, the reciprocatingly rotational power is transmitted from theoutput shaft to the driving arm 322 in order to drive the resilient arm321 to rotate. It is appreciated that the rotatable arm 32 can beembodied as the output shaft that the motorized unit 312 generates thereciprocatingly rotational power directly to the rotatable arm 32.

Accordingly, the drive gear unit 323 comprises a first gear coupled atthe shaft of the motorized unit 312 and a second gear couple at thedriving arm 322 of the rotatable arm 32, wherein the first and secondgears are meshed with each other to transmit the reciprocatinglyrotational power from the motorized unit 312 to the rotatable arm 32.

In order for the user to couple the thread with the epilation apparatus,the present invention further comprises a thread unit 40 to incorporatewith the thread 10. The thread unit 40 has two thread slots 41indentedly provided at the two free ends of the holding arms 22respectively, two thread couplers 42 provided at the free ends of thethread 10 to detachably couple with the holding arms 22 respectively,and a thread retainer 43 provided at the mid-portion of the thread 10 todetachably couple with the rotatable arm 32.

Each of the thread couplers 42 is embodied as an enlarged couplingelement preferably tied at the respective free end of the thread 10,wherein a size of the thread coupler 42 is larger than a width of thethread slot 41, such that when the thread 10 is held along the threadslot 41, the thread coupler 42 will retain the thread 10 at the threadslot 41 by the tension of the thread 10, so as to detachably couple thefree end of the thread 10 at the corresponding free end of the holdingarm 22.

The thread retainer 43 is provided at the mid-portion of the thread 10,preferably at the mid-point of the thread 10. The thread retainer 43 isembodied as a retaining ring to couple with the free end of therotatable arm 32. According to the preferred embodiment, the free end ofthe resilient arm 321, as a compression spring, forms a hook end toengage with the thread retainer 43 so as to hold the mid-portion of thethread 10 in position.

Alternatively, the thread retainer 43A can be integrally formed at thefree end of the rotatable arm 32 as shown in FIG. 6B, wherein the thread10 can pass through the thread retainer 43A to hold the mid-portion ofthe thread 10 in position. It is worth mentioning that when two ends ofthe thread 10 are held at the free ends of the holding arm 22respectively, the mid-portion of the thread 10 will be self-adjusted tobe held by the thread retainer 43A.

In order to use the epilation apparatus, the present invention furtherprovides a method of removing hair the epilation apparatus whichcomprises the following steps.

(1) Couple two free ends of the thread 10 at two free ends of theholding arms 22 respectively. According to the preferred embodiment, thefree ends of the thread 10 are detachably coupled at two free ends ofthe holding arms 22 by the thread couplers 42.

(2) Couple the mid-portion of the thread 10 at the free end of therotatable arm 32. According to the preferred embodiment, the mid-portionof the thread 10 is detachably coupled at the free end of the rotatablearm 32 by the thread retainer 43.

Accordingly, in the step (2), the folding tab 241 is folded to exposethe free end of the rotatable arm 32. Therefore, the user is able tocouple the thread retainer 43 to the rotatable arm 32 easily. Once theengagement therebetween is completed, the folding tab 241 can be foldedback on the upper side of the housing 21.

It is worth mentioning that after the mid-portion of the thread 10 isdetachably coupled at the rotatable arm 32, the thread 10 will form aV-shaped configuration and will define two equally length threadsections. Each thread section of the thread 10 is extended from the freeend of one of the holding arms 22 to the free end of the rotatable arm32.

(3) Apply the rotational force at the rotatable arm 32 toreciprocatingly rotate the rotatable arm 32 for twisting the thread 10to simulate the threading motion. Accordingly, the rotatable arm 32 ispowered by the motorized unit 312 to generate the reciprocatinglyrotational power to the rotatable arm 32. When the rotatable arm 32 isrotated forwardly to twist the thread 10, the two thread sections of thethread 10 will be wound to form the wound portion starting from therotatable arm 32 toward the free ends of the holding arms 22. When therotatable arm 32 is kept rotating, the wound portion of the thread 10will be increased towards the free ends of the holding arms 22. When therotatable arm 32 is rotated backwardly, the wound portion of the thread10 will be reduced towards the free end of the rotatable arm 32. Thewinding manner of the thread 10 will simulate the threading motion toremove the hair when the thread 10 is placed on the skin of the user asthe traditional threading technique.

In the step (3), the method further comprises a step of applying theresilient force at the thread 10 to self-adjust a tension of the thread10. Accordingly, the rotational force and the resilient force areapplied to the thread 10 by the rotatable arm 32 at the same time. Inother words, the resilient arm 321 will be driven to rotate and will bestretched out at the same time when the wound portion of the thread 10is increased towards the free ends of the holding arms 22. It is worthmentioning that the free end of the resilient arm 321 may be pulled outof the front side 211 of the housing 21 through the through slot 23 whenthe wounding portion of the thread 10 reaches its maximum length, so asto prevent the thread 10 being broken by its tension. The resilient arm321 will be driven to rotate and will be pulled back at the same timewhen the wound portion of the thread 10 is decreased towards the freeend of the rotatable arm 32. In other words, the rotatable arm 32 isarranged to control the length of the wound portion of the thread 10. Itis worth mentioning that the resilient force by the resilient arm 321will be adjusted by the tension of the thread 10. When the tension ofthe thread 10 increases, i.e. increasing the length of the wound portionof the thread 10, the stretching force of the resilient arm 321 will becorrespondingly increased. It is worth mentioning that the resilientforce is applied perpendicular to the first side 211 of the body 20. Inparticular, the resilient force is aligned with the winding direction ofthe thread 10.

It is worth mentioning that after the threading operation is completed,the thread 10 should be removed from the epilation apparatus anddisposed for one time use.

One skilled in the art will understand that the embodiment of thepresent invention as shown in the drawings and described above isexemplary only and not intended to be limiting.
